evaluation of the pain relief effect of battlefield acupuncture on patients with chronic low back pain due to lumbar spine degeneration.

Conditions: Spondylosis Lumbar

Summary: the global burden of disease's 2023 study shows that lower back pain affects over 619 million people worldwide, with projections reaching 843 million by 2050. it is a common symptom of lumbar spine degeneration, with 84.2% of patients experiencing it. to address this issue, vietnam's ministry of health has released guidelines on "lumbar spine pain" (yêu thống), combining traditional and modern medicine, including acupuncture, to alleviate pain. however, to achieve better treatment outcomes, the combination of multiple interventions, such as different types of acupuncture, is required. additionally, the usaf's integrative medicine and acupuncture center released guidelines in 2021 for battlefield acupuncture (bfa), a rapid, safe, and effective pain relief method. internationally, there are studies on bfa for various types of pain, including lower back pain, but none in vietnam. therefore, the investigators conducted this study to evaluate the effects of bfa combined with electroacupuncture and pain medication on chronic lower back pain patients with lumbar spine degeneration in vietnam.

Eligibility criteria:
inclusion criteria: * patients aged 20 years and older. * patients diagnosed with lumbar spine degeneration (imaging and clinical criteria according to the "guidelines for diagnosis and treatment of musculoskeletal diseases" - ministry of health of viet nam 2014; aafp-2024). * patients with back pain with a vas score of ≥ 50mm, continuous or recurrent with the same initial diagnosed cause, lasting from the time of initial diagnosis to the time of study participation for ≥ 3 months. * individuals who have never used auricular acupuncture. * voluntarily agree to participate in the study. exclusion criteria: * individuals with cognitive disorders (glasgow \< 13 points). * individuals are allergic to any component of the ear acupressure seeds, or experiencing anxiety, fear of needles, or with a history of acupuncture syncope. * patients with symptoms of saddle anesthesia, urinary or fecal incontinence, paresthesia or muscle atrophy, progressive muscle weakness. * history of cancer or currently undergoing cancer treatment, or unexplained weight loss. * patients who are awakened at night due to back pain. * patients contraindicated the medication used in the study: paracetamol. * pregnant or breastfeeding women. * patients are currently experiencing systemic infection. * individuals with unhealed wounds, ear or lumbar region infections. * currently participating in an intervention study with another drug or device.
